,'Be itlrnown that we, GIL-BERT C. LANDIS and-'JAco H., SM1 'ru, both citizens of the United States, residing in lVadsworth, Ohio,

and Rittman, Chim-respectively, have invented certain Improvements in Electrolytic Cells, o f which the following is a specifica- One object of our invention is to provide novel means for/'reducing or maintaining at a relatively low pointthe temperature ofthe liquid in an' electrolytic cell; it being especially desired that the-means employed for this purpose shallbe of such a nature as not 'to affect the current capacity of the electrodes. We further desire to provide an electrolytic cell with improved means for holding its various electrodes in place. These -objects and other advantageous ends we? se' cure as hereinafter sept forth, reference being had to the accompanying drawings, in which Figure 1, is a horizontal section of a por# tion of an electrolytic cell' constructed 'according tol our invention; Fig. 2, is a vertical section on the line-2 2, Fig. l, and Fig. 3, is a vertical section lon the line 3-3, Fig. 2.

In the above drawings, A represents a suitable container for the cell, preferably made of stoneware, slate or' other material incapable of conducting an electric current. This has its two opposite sides provided with parallel vertically extending ribs a placed at suitable distances apart and holding in the spaces between them the electrodes B and B. Said electrodes extend into the recesses and a liquid tight joint is formed between each edge of an electrode and the adjacent wall of the container A b v sone suitable cement, indicated at b," of a composition-unaffected by the electrolyte' employed in the cell. .From Fig. 2, it will be noted that all of the electrodes B extend down to and rest upon the bottom ot the container, while their upper edges are some distance below the top -edge of said containerso vas to permit the passage over them ot' the electrolyte as it-v flows through thel cell. The intermediate electrodes B' on the other hand, have their top edges at about the height ot' the top edge of the container, 'or atleast at such a level ELnC'rRoLYTIc CELL;

As shown best in F ig. 3, there is 'betweeneach two electrodes a coil or other suit-able mass of' tubing C, formed of glassor other material, lncapable 'of conducting an electric current'. 4One end of each of the coils C'is' connectedl toa supply"main D connected to a source of cooling liquid, such as Wateror D- whichrn'ay be led to any suitable waste in its treatment is caused to circulate through Patented Nov. 1, 1910.

I t will'be understood thatthese lat'-v ter are constructed of suitable material and provided withthe necessary terminals in the manner well understood in the art, and 'in order that the temperature of'this electrolyte while under treatment may be kept from ris-- ing to an objectionable oint, water or'other desired Vcooling or re 'gerating liquid is caused to'pass throu h the various cooling pipes C, being supp led from pi e D and discharged into the pipe D. By t is means, injury to the electrodes from -abnormaltemf peraturesA of the electrolyte is prevented, and by using coils or convolutions of the cooling tubes, especially if they be arranged as shown, the cur'rent capacity," of theyarious electrodes is not materially diminished or the o eration of the cell objectionably afecte By the employment of the particular construction shown for holding the elec-4 trodes in place,'lthese are properly spaced and liquid tight. joints between their edges and the adjacent walls of the' container are easily secured and maintained.

An electrolytic cell consist-ing of a container; two series ofelectrodes mounted in said container to form a tortuons path` through the same for the electrolyte; `a series v'ofl tuHe-s' of.electrice1 noncomlucting manames to thsepeccaton, in'thepresence stantiall;r parallel convolutions; one of said terial each in the form of a series of sub'- of two subscribing-witnesses.
